Conspiracy under the UCMJ does not require that the underlying criminal objective was achieved. The agreement between two or more persons to commit an offense, combined with an overt act by one of them in furtherance of that agreement, is sufficient to establish the charge. A soldier who agreed to participate in a scheme that was discovered and interrupted before any harm was done can still face a conspiracy charge for the agreement itself.
This structure makes conspiracy a powerful tool for prosecutors. It allows charges to be brought earlier in the process, and it can be used to hold multiple individuals accountable even when direct evidence of each person’s role in the underlying conduct is limited. The defense must examine whether a genuine agreement existed, whether the government can prove the overt act requirement, and whether any of the accused took steps to withdraw from the conspiracy before it progressed to a point of no return.
The Elements of Conspiracy Under the UCMJ
Conspiracy under Article 81 of the UCMJ consists of two required elements: an agreement between two or more persons to commit an offense under the UCMJ, and an overt act by one of the parties in furtherance of the agreement. The agreement element requires that the parties had a meeting of the minds on the criminal objective. A casual conversation about committing a crime, without a genuine agreement to proceed, is not a conspiracy. The overt act element requires that at least one member of the conspiracy took some step, however minor, toward carrying out the agreed plan.
The completed offense is not an element. This is the feature of conspiracy law that surprises most people who encounter it for the first time. The agreement to commit the crime and the overt act in furtherance of it are sufficient for the charge, regardless of whether the underlying plan succeeded, failed, or was abandoned before execution. This means that participants in a scheme that was detected and stopped at an early stage can face conspiracy charges even if no harm was actually done.
Why the Underlying Crime Does Not Have to Be Completed
The incompletion of the object offense is built into the conspiracy framework by design. The crime of conspiracy is complete when two or more people agree to commit an offense and one of them takes an overt act in furtherance of that agreement. The object offense itself never needs to be carried out. A service member who agrees with another to steal equipment, takes a single step toward that goal, and then has a change of heart has already committed conspiracy under Article 81 at the moment the overt act was taken.
This feature of conspiracy law is what makes it so useful to prosecutors in cases where the planned offense was interrupted, abandoned, or unsuccessful. The government does not need to prove that the plan was executed. It needs to prove the agreement and the overt act. Those two elements are often easier to establish than the elements of the completed offense, and the punishment for conspiracy can be substantial even when nothing actually happened.
How Prosecutors Use Overt Acts to Satisfy the Conspiracy Elements
The overt act requirement under Article 81 is modest. Almost any act taken in furtherance of the agreement, no matter how preliminary, satisfies it. Drafting a plan, acquiring materials, conducting reconnaissance, communicating with co-conspirators about logistics, or taking any preparatory step connected to the agreed objective can constitute an overt act. The act does not need to be independently criminal, and it does not need to bring the conspirators close to completion of the object offense.
Prosecutors building a conspiracy case look for the earliest concrete steps and document them thoroughly. A text message exchange about a planned theft, a meeting to discuss logistics, a request for information that would facilitate the offense: each of these can serve as the overt act that completes the conspiracy elements. Defense counsel must examine the alleged overt acts carefully to ensure they actually satisfy the requirements and to identify any act that was not in furtherance of the agreement or that preceded the formation of any agreement.
How Abandonment Affects a Conspiracy Charge
A service member who withdraws from a conspiracy before the object offense is carried out may have a partial defense under some circumstances, but the withdrawal defense is narrow and difficult to establish. To qualify as a legally effective withdrawal, the service member must take affirmative steps to communicate their withdrawal to all co-conspirators, must do so in time for the co-conspirators to abandon the plan, and must not merely be passive in the face of the continuing conspiracy.
Withdrawal does not eliminate liability for the conspiracy itself if the conspiracy was already complete at the time of withdrawal. Once the agreement was formed and an overt act was taken, the conspiracy offense was complete. Withdrawal at that point prevents the withdrawing co-conspirator from being liable for subsequent acts by the remaining conspirators, but it does not undo the conspiracy charge based on what had already occurred.
The Role of Co-Conspirator Statements at Trial
One of the most significant evidentiary consequences of a conspiracy charge is the admissibility of co-conspirator statements. Under Military Rule of Evidence 801(d)(2)(E), a statement made by a co-conspirator during the course and in furtherance of the conspiracy is not hearsay and may be admitted against any member of the conspiracy. This means that what one co-conspirator said to a third party, in a conversation the accused never participated in, can be admitted against the accused if the statement was made during and in furtherance of the conspiracy.
This rule creates substantial evidentiary exposure for service members charged with conspiracy. The government can use statements made by a co-conspirator who has since pleaded guilty and agreed to cooperate, statements captured in recorded communications, and statements made to witnesses who are outside the conspiracy, all potentially against the accused who never made those statements. Defense counsel must understand the scope of this rule and challenge the admissibility of any co-conspirator statement that does not satisfy all of the conditions for admission.
